write_script() would allow you to drop the #!/bin/sh and chmod lines.

Rather than hard-coding this output, generating it would make the test
script less fragile:

Each -c/-C case fails for me when trying to read $empty_object. For example:
fatal: Failed to read object 'e69de29bb2d1d6434b8b29ae775ad8c2e48c5391'.
not ok 5 - 'git notes add -c "$empty_blob"' removes empty note
